SLS on track to CDR as engineers work though a baffling issue

January 5, 2013 by Chris Bergin

As the Space Launch System (SLS) heads on to the path towards its Critical Design Review (CDR), engineers are close to mitigating an issue relating to the core stage’s slosh baffles. The work on the baffle design and placement is part of the stability analysis for the HLV’s ride uphill.

SLS PDR to CDR:

In the latest milestone to end 2012 – the Preliminary Design Review (PDR) – SLS passed all 12 key criteria, according to information provided to L2, with only five “yellow” risks, all of which are expected to be addressed. In other words, SLS is suffering from zero critical design or schedule threats at this time.

This is a refreshingly positive overview when compared to the numerous “red” issues suffered by Ares 1 at this same stage of development.
